The original proposed refrigerant was a paramagnetic salt, such as cerium magnesium nitrate.
2.
This precooling is often provided by the mixing chamber of a dilution refrigerator or a paramagnetic salt.
3.
This anomaly is usually seen in paramagnetic salts or even ordinary glass ( due to paramagnetic iron impurities ) at low temperature.
4.
In a paramagnetic salt ADR, the heat sink is usually provided by a pumped ( about 1.2 K ) or ( about 0.3 K ) cryostat.
5.
Dilution refrigerators had for many years supplanted paramagnetic salt ADRs, but interest in space-based and simple to use lab-ADRs has remained, due to the complexity and unreliability of the dilution refrigerator
6.
This is similar to the way that the ions in an aqueous paramagnetic salt solution ( such as an aqueous solution of copper ( II ) sulfate or manganese ( II ) chloride ) make the solution paramagnetic.
